A-Levels are usually studied over a 2 year period now. Since A-Levels are linear, there is no AS unless you are entered for them by your school. There are no "best" universities for Medicine. All medical schools are considered equal as you'll be studying the same thing in any medical school so a place anywhere is good.

The minimum A-Level requirements are AAA or above. However, this can differ depending on where you apply to. Other medical schools like UCL ask for A*AA at A-Level. The process is lengthy. You have to have good GCSE's and A-Levels. In addition, you have to complete and get a good score in UKCAT/BMAT depending on where you are applying. You need lots of volunteering and experience in hospitals. This all needs to be on your application then once it's sent off, you'll be invited to interviews then acceptance or rejection.
